CheckNumber's Telegram checker tells you whether a phone number is registered on Telegram and how recently that account was online, without ever messaging the person or storing the number.

What CheckNumber detects for Telegram
Registration status
Confirms whether the phone number has a registered Telegram account (yes or no), so you can filter out unregistered numbers before outreach.
Days since last online
Returns how many days since the account was last active on Telegram, so you can prioritise live users over dormant ones.
Profile photo
Returns the public Telegram profile photo URL when available. Automated analysis may provide probabilistic age-range and gender estimates.
Estimated age
Provides a probabilistic age-range estimate from an available public profile photo.
Gender
Provides a probabilistic gender estimate from an available public profile photo.
Account and activity details
Depending on the task type, returns username or UID, first and last name, last-online time, active days, and Telegram Premium status when available.

Telegram FAQ
Can I check phone numbers against Telegram in bulk?
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, choose the task type you need, then download a result file with a registration verdict for every number. You are billed only for successful checks.
Does a Telegram check message or notify the person?
No. The check is passive and reads registration and public profile signals only. Nothing is sent to the number, and the account owner is never contacted or notified.
What profile details can the Telegram checker return?
With the avatar task type, a registered number can return the public profile photo URL and probabilistic age-range and gender estimates, plus available username or UID, first and last name, last-online time, active days, and Premium status. Image-derived estimates may be incomplete and should not be used to make decisions about individuals.
Is there a free trial for the Telegram checker?
Yes. New accounts receive 1,000 free checks on signup with no credit card, and every Telegram check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
